<a name="GstDirectControlBinding.description"></a><h2>Description</h2>
<p>A value mapping object that attaches control sources to gobject properties. It
will map the control values directly to the target property range. If a
non-absolute direct control binding is used, the value range [0.0 ... 1.0]
is mapped to full target property range, and all values outside the range
will be clipped. An absolute control binding will not do any value
transformations.</p>
